[En-Nut-Discussion] NutGetTickClock rounding (again)

[Henrik Maier]

I agree, then let's implement it. 

Henrik

274 static inline unsigned long msecs_to_jiffies(const unsigned int m)
275 {
276         if (m > jiffies_to_msecs(MAX_JIFFY_OFFSET))
277                 return MAX_JIFFY_OFFSET;
278 #if HZ <= MSEC_PER_SEC && !(MSEC_PER_SEC % HZ)
279         return (m + (MSEC_PER_SEC / HZ) - 1) / (MSEC_PER_SEC / HZ);
280 #elif HZ > MSEC_PER_SEC && !(HZ % MSEC_PER_SEC)
281         return m * (HZ / MSEC_PER_SEC);
282 #else
283         return (m * HZ + MSEC_PER_SEC - 1) / MSEC_PER_SEC;
284 #endif
285 }
